Re: Converting to JSON in CDS view

2023-08-24T14:37:17+02:00

where are you calling this from?

in HANA DB - you could use the "FOR JSON"

in OData - exposing your CDS view should be done by default (Odata v4)

Re: Not nullable input field is not validated as mandatory in Fiori app

2023-08-24T14:47:30+02:00

are there any local annotations in this app that may be overwriting the behavior of the field in the backend?

try refreshing the metadata and see if there are local annotations

Re: Calculated Column in Graphical Calculation View

2023-08-24T14:52:21+02:00

you have data shown at two levels.. raw and aggregated... create one view to do the first level (order, item, store).

then create another view to aggregate it.... then join it in a 3rd view... OR

if you're can use sqlscript, you can do it all within one function. then consume it from a view.

Re: Does a REST API exist for initiating SAP HANA DB within SAP BTP?

2023-08-29T15:01:32+02:00

no, I dont think there is a REST API for that... however, once a DB instance is provisioned, you may interact with it via the hana-cli. https://www.npmjs.com/package/hana-cli hope this is also helpful

Fall begins, Football, Devtoberfest, Tech Ed and more

Hello Dallas community,

now that summer is coming to an end, the kids are back to school and we need to close the year strong, I was thinking about the events coming up.

American Football is one of those activities that people look forward to on the weekends. I am not a college football fan but it has started and games are played on saturday. Then, on Sunday, we can look forward to most of the NFL games. Which team are you cheering for? #GoPackGo #GreenBay

SAP Devtober fest: I have not participated in this event before but I think I want to check it out this year. Here are more details about it. https://developers.sap.com/devtoberfest.html

In the near future (a couple of months) we will be having the ASUG Tech connect in New Orleans and then a virtual tech ed for the USA. Anyone from Dallas going to NOLA?

Anyone able to help organize a tech ed watch party? maybe even have a SIT or Stammtisch?

Please share your comments about one or all events and also if you or your company are able to help host one of the watch parties, SIT, or Stammtisch. Looking forward to the responses.

ASUGTechConnect 23 - day 1

ASUGTechConnect - New Orleans 2023

SAP Fiori Best Practices Roundtable

Peter Spielvogel had a short/high level presentation about #SAPFiori, the different floorplans and different ways #Fiori works (web/mobile/conversational UX)

Questions from the audience mainly were related to loading many tiles in the FLP and seeing performance issues. This was a common scenario for many attendees; a shared opinion was that maybe the “many tiles” needed to be reduced into different catalogues and/or seeing how the people accessing these #FLPs. Maybe even analyze the roles/hierarchy of the business groups to see if additional groups/layers could be introduced. In one of my previous projects, we experienced something similar and an approach we had was to benchmark the time in the FLP to load a tile, record the time the OData service took to return the data and trace the time in the CDS view to analyze how long it took at each layer. It seems like a straightforward approach from the development point of view however, there may be other culprits to look at one’s landscape; for example: network latency (VPN, external connection, internal company connections, etc.)

What about offline capabilities? The suggestion was that Fiori web applications are considered connected applications, while mobile native applications are supposed to be used for offline capabilities. Moreover, another suggestion was to use screen personas for mobile apps.

Another scenario that someone shared was a short view of business object for a phone screen, however, when the phone rotated to a horizontal position, additional details were shown. I think I have seen that in other scenarios but not in an SAP scenario. Good thinking!

Understanding SAP BTP Reference Architecture for Multiple-Platform Environments

Steffem Pietsch had a presentation about the different Hyperscalers and how the #BTP can work with these hyperscalers. There were some interesting additional public topics and links shared such as the AWS graviton service, the SAP private link service and in my opinion the most important for me was the Reference Architecture in SAP Discovery Center. You can find all the info here: https://discovery-center.cloud.sap/index.html

What is a Hyperscaler--> large cloud service providers that offer large computing elastic services for companies. Hyperscalers such as #AWS, #Azure, #Google are the common players in this area.

AWS Graviton--> AWS Graviton is a family of processors designed to deliver the best price performance for your cloud workloads running in Amazon Elastic Compute Cloud (Amazon EC2). https://aws.amazon.com/ec2/graviton/

SAP Private Link --> AWS currently has a service called Private Link which is a service that provides private connectivity between VPCs, on-premise networks, and AWS services without exposing traffic in the public internet. SAP private link leverages what AWS has done and further included connectivity between AWS accounts/services and BTP services. With the initial release, the following AWS services are included: AWS S3 (storage service), AWS SNS (notification service), AWS SQS (queue service), AWS SES (email service) and AWS Aurora (RDS API operations).

https://aws.amazon.com/blogs/awsforsap/how-to-connect-sap-btp-services-with-aws-services-using-sap-private-link-service/

Further, there was a small section towards the end about SAP Joule which is the copilot / digital assistant for SAP BTP. https://www.sap.com/products/artificial-intelligence/ai-assistant.html

How PG&E used SAP Fiori Elements and CDS views to streamline Financial Process

Guy de Bruyn and Meghana Vyas did an amazing presentation explaining an internal solution they developed to overcome an issue their business had in the financial area. This solution involved receiving invoices, acknowledging them, and then providing approvals to such invoices. The business scenario was thoughtfully analyzed and solved by using a combination of new technologies such as #CAP, #Fiori-Elements, and extensions, #CDSViews, and from their demo, one of my favorite additions was the Training videos they provided their users. This presentation aligns more to my experience (HANA and Fiori) I think it was my favorite one from day 1.

Earlier in the year, I wrote a blog about #CAP, how to create a simple application and adding more props to it. It can be read here, https://blogs.sap.com/2023/04/14/my-head-is-on-the-cloud-my-learnings-about-capm/

I am looking forward to day two of #ASUGTechConnect, learning new things, connecting with new people and seeing what others are doing. what is/was your best presentation or learning from day 1?

2024 Events

2024-03-15T16:10:48.340000+01:00

hello Dallas group,

with 6 new members this year and almost at the end of the first quarter of 2024, it is time to start thinking about what events (knowledge sharing, social or both) would you like to help with, participate or suggest for this year... we should have enough people to do something again this year. Feel free to suggest or lead one of them.
